[0031] See alsoFigure 1 , Figure 1 is a part structure schematic diagram of the cooking equipment provided in the present application. The present application provides a burner 100. The burner 100 is used to be arranged in a cooking equipment 1000 which can be an oven, a smoking and roasting all-in-one machine or a gas stove, but is not limited thereto. The present application takes the cooking equipment 1000 as an oven as an example for illustration. The cooking equipment 1000 comprises the burner 100, a box body 200 and a fan 300. The burner 100 and the fan 300 are arranged in a cooking cavity 200a of the box body 200. The box body 200 is a basic carrier of the cooking equipment 1000, and can play a role of bearing and protecting the parts of the cooking equipment 1000. The burner 100 can serve as a heating source of the cooking equipment 1000. The burner 100 is used to ignite fuel, and radiate the heat generated by the combustion of the fuel to the cooking cavity 200a in the form of infrared radiation, so as to cook food in the cooking cavity 200a. The fan 300 can promote the circulation of fluid in the cooking cavity 200a, so as to uniformly distribute the heat in the cooking cavity 200a, and ensure that the food can be uniformly heated in the cooking process, thereby improving the cooking effect.

[0032] Please refer to Figures 2-3 , Figure 2 is a three-dimensional structure schematic diagram of the burner provided in the present application; Figure 3 is an exploded structure schematic diagram of the burner provided in the present application. The burner 100 comprises a ring-shaped shell 110 and a ring-shaped combustion assembly 120. The ring-shaped shell 110 forms a ring-shaped accommodating cavity 111 with an opening 111a and a drainage port 112 which is in communication with the ring-shaped accommodating cavity 111. The ring-shaped combustion assembly 120 is arranged on the opening 111a. The air inlet of the fan 300 is in communication with the cooking cavity 200a through the ventilation hole 113 formed by the ring-shaped shell 110.

[0033] The drainage port 112 is used to introduce the mixed fluid of the fuel and the combustion-supporting agent such as air into the ring-shaped accommodating cavity 111. The ring-shaped structure of the ring-shaped accommodating cavity 111 is beneficial to the further mixing and diffusion of the fuel and the combustion-supporting agent such as air, so that the fuel and the combustion-supporting agent such as air can be efficiently mixed and fill the entire ring-shaped accommodating cavity 111, and the flow of the mixed fluid of the mixed fuel and the combustion-supporting agent such as air reaching different positions of the ring-shaped combustion assembly 120 is consistent, so that the heat radiated by different positions of the ring-shaped combustion assembly 120 to the cooking cavity 200a is the same. Meanwhile, the ventilation hole 113 is used to connect the air inlet of the fan 300 and the cooking cavity 200a, and can promote the circulation of fluid in the cooking cavity 200a, so that the heat in the cooking cavity 200a can be uniformly distributed, and therefore the food cooked in the cooking cavity 200a can be uniformly heated, thereby improving the cooking effect of the cooking equipment 1000.

[0034] It should be noted that in the present application, the mixed fluid of the fuel and the combustion-supporting agent such as air can be simply referred to as fluid.

[0035] In some embodiments, the burner 100 further comprises a mounting plate 131. The mounting plate 131 is formed with an air inlet 131a and air outlets 131b. The air inlet 131a is formed in the middle of the mounting plate 131. The air outlets 131b are formed at the edges of the mounting plate 131. The air outlets 131b can be arranged opposite to each other on both sides of the mounting plate 131, and the air inlet 131a is located between the two air outlets 131b; or the air outlets 131b can be arranged around the edges of the mounting plate 131, and the air outlets 131b are arranged around the air inlet 131a. The arrangement of the air inlet 131a and the air outlets 131b can be determined according to specific conditions, as long as the air inlet 131a is formed in the middle of the mounting plate 131 and the air outlets 131b are formed at the edges of the mounting plate 131.

[0036] The mounting plate 131 has a first side and a second side arranged opposite to each other. The first side of the mounting plate 131 is arranged towards the inner wall of the cooking cavity 200a to form an air duct between the first side of the mounting plate 131 and the inner wall of the cooking cavity 200a. The air duct is in communication with the air inlet 131a and the air outlets 131b. The air duct is used to arrange the fan 300. The annular housing 110 is arranged at the second side of the mounting plate 131 opposite to the first side, and the ventilation hole 113 is arranged in communication with the air inlet 131a. The central axis of the ventilation hole 113 can coincide with the central axis of the annular housing 110, or the central axis of the ventilation hole 113 can be parallel to the central axis of the annular housing 110.

[0037] The fan 300 is used to suck air through the ventilation hole 113 and the air inlet 131a and send air to the cooking cavity 200a through the air outlets 131b to promote the circulation of fluid in the cooking cavity 200a. The fan 300 sucks air through the ventilation hole 113 of the annular combustion assembly 120 and the air inlet 131a in the middle of the mounting plate 131, and sends air to the cooking cavity 200a through the air outlets 131b at the edges of the mounting plate 131, which can promote the circulation of fluid in the cooking cavity 200a, promote the diffusion of heat, and thus make the heat distribution in the cooking cavity 200a more uniform, further improving the uniformity of heat distribution in the cooking cavity 200a.

[0038] In some embodiments, the burner 100 further comprises a mounting member 140. One end of the mounting member 140 is connected with the annular housing 110, and the other end is connected with the mounting plate 131 or used to connect with the box body 200.

[0039] The mounting piece 140 is used to mount the annular housing 110 on the mounting plate 131 or the cabinet 200 of the cooking device 1000, so as to mount the burner 100 on the mounting plate 131 or the cabinet 200 of the cooking device 1000, thereby improving the stability of the burner 100 structure, so that the annular combustion assembly 120 can stably radiate heat to the cooking cavity 200a, and the cooking effect of food is improved.

[0040] In some embodiments, the mounting piece 140 comprises a first mounting portion 141, an extension portion 142 and a second mounting portion 143 connected in sequence. The extension portion 142 is arranged perpendicularly to the first mounting portion 141 and the second mounting portion 143, and the first mounting portion 141 and the second mounting portion 143 are located on opposite sides of the extension portion 142. The first mounting portion 141 is connected to the outer side wall of the annular housing 110, the extension portion 142 is at least partially located on the side edge of the mounting plate 131, and the second mounting portion 143 is used to connect to the cabinet 200.

[0041] The mounting piece 140 is composed of the first mounting portion 141, the extension portion 142 and the second mounting portion 143, and has high strength. The first mounting portion 141, the extension portion 142 and the second mounting portion 143 can be a fixed connection structure, that is, the first mounting portion 141, the extension portion 142 and the second mounting portion 143 can be a split structure, which can be fixedly combined together by welding, riveting, bolt connection and the like. Of course, the first mounting portion 141, the extension portion 142 and the second mounting portion 143 can also be an integral molding structure, thereby reducing the assembly process and improving the sealing performance.

[0042] In some embodiments, the annular housing 110 comprises an annular bottom shell 114, a first side shell 115 and a second side shell 116. The first side shell 115 is arranged around the inner periphery of the annular bottom shell 114 and extends towards the annular combustion assembly 120, so as to form the ventilation hole 113. The second side shell 116 is arranged around the outer periphery of the annular bottom shell 114 and extends towards the annular combustion assembly 120, so as to form the annular accommodation cavity 111 together with the first side shell 115 and the annular bottom shell 114.

[0043] Any one of the first side shell 115, the annular bottom shell 114 and the second side shell 116 is a closed structure connected head to tail. The connection between the first side shell 115 and the annular bottom shell 114 and the connection between the annular bottom shell 114 and the second side shell 116 are both smooth transitions, which can reduce the friction of the fluid at the connection between the first side shell 115 and the annular bottom shell 114 and at the connection between the annular bottom shell 114 and the second side shell 116, thereby reducing the flow resistance and friction noise of the fluid. The first side shell 115 is arranged around the inner periphery of the annular bottom shell 114 and extends towards the direction of the annular combustion assembly 120 to form a ventilation hole 113 on the side of the first side shell 115 away from the annular containing cavity 111, and the first side shell 115 is arranged around the ventilation hole 113. In some embodiments, the inner periphery of the annular bottom shell 114 can be circular, and at this time the first side shell 115 can be cylindrical or conical. In other embodiments, the inner periphery of the annular bottom shell 114 can be polygonal, and at this time the first side shell 115 can be prismatic or pyramidal. The specific shape of the inner periphery of the annular bottom shell 114 and the first side shell 115 can be selected according to actual conditions, as long as the ventilation hole 113 can communicate with the air inlet 131a and the cooking cavity 200a of the cooking device 1000.

[0044] In some embodiments, the outer periphery of the annular bottom shell 114 can be circular, and at this time the second side shell 116 can be cylindrical or conical. In other embodiments, the outer periphery of the annular bottom shell 114 can be polygonal, and at this time the second side shell 116 can be prismatic or pyramidal. The specific shape of the outer periphery of the annular bottom shell 114 and the second side shell 116 can be selected according to actual conditions. The embodiments of the present application take the outer periphery of the annular bottom shell 114 as circular and the second side shell 116 as conical as an example for description.

[0045] In some embodiments, the first side shell 115 and the second side shell 116 are both conical, wherein the diameter of the first side shell 115 gradually decreases in the direction from the mounting plate 131 to the annular combustion assembly 120, and the diameter of the second side shell 116 gradually increases in the direction from the mounting plate 131 to the annular combustion assembly 120, so that the flow area of the annular containing cavity 111 gradually increases in the direction from the mounting plate 131 to the annular combustion assembly 120, which not only can improve the uniformity of the mixing of the fuel and the combustion-supporting agent such as air in the annular containing cavity 111, but also has a fluid guiding effect, which can accelerate the flow speed of the fluid to the annular combustion assembly 120 and improve the heating efficiency.

[0046] In some embodiments, the first side shell 115, the annular bottom shell 114 and the second side shell 116 can be fixedly connected structures, that is, the first side shell 115, the annular bottom shell 114 and the second side shell 116 can be split structures and can be fixedly combined together by welding, bonding or the like. Of course, the first side shell 115, the annular bottom shell 114 and the second side shell 116 can also be integrally formed structures, thereby reducing the assembly process and improving the sealing performance.

[0047] In some embodiments, please refer to Figure 4 , Figure 4 is a structural schematic view of the cooperation of the annular shell, the injection pipe and the mounting member of the burner provided in the present application. The inner wall of the annular bottom shell 114 is formed with a first bottom surface 1141 and a second bottom surface 1142 connected in sequence. The first bottom surface 1141 is located on the side of the annular bottom shell 114 close to the flow inlet 112 and is parallel to the plane on which the mounting plate 131 is located. The second bottom surface 1142 is inclined from the two sides of the first bottom surface 1141 toward the direction of the annular combustion assembly 120.

[0048] The tail end of the first bottom surface 1141 is connected to the head end of the second bottom surface 1142, the tail end of the second bottom surface 1142 is connected to the head end of the first bottom surface 1141, and the tail end of the first bottom surface 1141 and the head end of the second bottom surface 1142 and the tail end of the second bottom surface 1142 and the head end of the first bottom surface 1141 are smoothly transitioned. The first bottom surface 1141 and the second bottom surface 1142 are connected in sequence to form a closed annular bottom shell 114. The first bottom surface 1141 is located on the side of the annular bottom shell 114 close to the flow inlet 112, and the second bottom surface 1142 is located on the side of the annular bottom shell 114 away from the flow inlet 112. In order to make the fluid uniformity of the annular containing cavity 111 relative to the area of the second bottom surface 1142 consistent with the fluid uniformity of the annular containing cavity 111 relative to the area of the first bottom surface 1141, the second bottom surface 1142 is arranged to be inclined from the two sides of the first bottom surface 1141 toward the direction of the annular combustion assembly 120, so that the second bottom surface 1142 is arranged to be inclined relative to the first bottom surface 1141. The second bottom surface 1142 can guide the flow of fluid to the side of the annular containing cavity 111 away from the injection pipe 150, thereby improving the uniformity of the fluid in the annular containing cavity 111. On the one hand, it is conducive to promoting the mixing of air and fuel, and on the other hand, it can further guide the mixed fluid of fuel and combustion-supporting agents such as air input from the flow inlet 112 to the space on the side of the annular containing cavity 111 away from the flow inlet 112, thereby improving the distribution uniformity of the mixed fluid of fuel and combustion-supporting agents such as air in the annular containing cavity 111, which can improve the thermal radiation uniformity of the burner 100, so that the fuel can be uniformly burned on the annular combustion assembly 120, thereby helping to improve the distribution uniformity of heat in the cooking cavity 200a.

[0049] In some embodiments, the first bottom surface 1141 and the second bottom surface 1142 have an included angle therebetween, and the included angle therebetween is 90-175°.

[0050] The included angle between the first bottom surface 1141 and the second bottom surface 1142 can be 90°, 96°, 98.8°, 100°, 105°, 107.5°, 110°, 113.5°, 115°, 118.8°, 120°, 123°, 126.5°, 127°, 130°, 133.5°, 135°, 136°, 138°, 139.5°, 140°, 142°, 145°, 148°, 150°, 155°, 158°, 160°, 164°, 166°, 168.5°, 170°, 171°, 173.5°, 175°, or a range between any two of the above values, for example, 90-115°, 90-135°, 115-135°, 120-135°, 135-142°, 135-160°, 135-175°, 140-160°, 160-175°, etc., as long as the included angle between the first bottom surface 1141 and the second bottom surface 1142 is within the range of 90-175°. Preferably, the included angle between the first bottom surface 1141 and the second bottom surface 1142 is 135°.

[0051] In some embodiments, the first bottom surface 1141 and the second bottom surface 1142 are on the same plane.

[0052] In some embodiments, the annular combustion assembly 120 comprises an annular radiant member 121 arranged on a side of the annular combustion assembly 120 facing the cooking cavity 200a to radiate heat to the cooking cavity 200a, and the annular radiant member 121 is a metal fiber material.

[0053] It should be noted that the metal fiber material can be formed by crossing, drying and sintering treatment of metal fibers, and the metal fibers can be fibers made of iron, nickel, chromium, aluminum and alloys thereof.

[0054] The annular radiant member 121 is a metal fiber material, so that the annular radiant member 121 has uniform air permeability, can radiate heat generated by fuel combustion to the cooking cavity 200a in the form of infrared radiation, improve heating uniformity, reduce the generation of pollutants such as nitrogen oxides and carbon monoxide, and at the same time, the annular radiant member 121 has good corrosion resistance and oxidation resistance, can be used stably for a long time in a high-temperature environment, and has a long service life.

[0055] In some embodiments, the annular combustion assembly 120 further comprises an annular baffle plate 122, which is arranged between the annular shell 110 and the annular radial member 121, and has a plurality of first openings 122a communicating with the annular accommodating cavity 111.

[0056] The annular baffle plate 122 is arranged on the side of the annular shell 110 facing the annular radial member 121, and the annular baffle plate 122 and the annular radial member 121 are sequentially arranged on the annular shell 110 to cover the opening 111a of the annular combustion assembly 120. The annular accommodating cavity 111 is located between the annular shell 110 and the annular baffle plate 122. The annular baffle plate 122 is provided with a plurality of first openings 122a communicating with the annular accommodating cavity 111, and the plurality of first openings 122a are uniformly distributed on the annular baffle plate 122. The first openings 122a play a role in distributing the fluid in the annular accommodating cavity 111, and can divide the flow path of the fluid flowing from the annular accommodating cavity 111 to the annular radial member 121, thereby ensuring that the fluid flow to different positions of the annular radial member 121 is consistent.
